Carb Date Code

[KNAPPY]

I just bought a Holley Carb for my 67 Z-28. The list# is 3910, with a part # 3916143-CT, The date code is 173. Did Holley make this carb in 1971 or could this be an error. It was suppose to be a 713 date code?

Knappy,
The carb you have is a service replacement. They built carbs after the original production year to use for replacements. Sometimes they didn't rebuild them, they just replaced them.

Yep, I'm with Mark on this one...

Thats what I thought, well I guess I am still looking for am early dated 3910 Holley ( Jan.- Feb. 1967). If any one out there has one I am interested. Thanks

I have a body dated '68 if you want a service replacement closer to to '67.

Thanks Marlin but I think I'll use this one until I find the right one. The guy I bought it from did not know how to read the date codes and told me it was a Jan. 67 carb. It has been rebuilt so I'll go with it for now.

Knappy,
I've had a service dated carb on my L72 car for years. I finally tracked down a '65 date coded restorable core. Getting it restored is one of the many things on my list. Definately use what you have until you get the one you want.

Ok, that's cool. I'm in it for a whopping $4, found it in bus in a junk yard. My buddy got the 4346 dated 12 of 68, another whopping $4 pricetag

[KNAPPY]

I wish I only paid 4 bucks for the one I bought!

I know! We moved about 400 carbs in this old bus to find 3-4 good ones, at $4 per, we would have moved 3x that amount for 3-4 more good ones

I think I have a 66 or 67 chevelle 396 Holley too, not sure anymore!
